So here's the deal: my three main collecting interests are #35 plates, Maine issues, and interesting non-passenger plates. Aside from the well-defined boundaries of #35 and Maine plates, I like plates that are a bit outside the norm. Plates with identifiers like "Junk," "Log Farm," or "Implement of Husbandry" are my kind of thing, though any non-typical non-passenger plate appeals to me. This list is by no means comprehensive, but it should give you a rough idea of what I'm after, and I'm always adding new discoveries to the list. Thanks for taking the time to look; I appreciate it.
